Thanks for your answer. The rational behind my proposal is why taking "from" when length.out=1, more than "to" or "NA", or " integer(0) " ?
This question seems basic. But is is not in certain situations, like when length.out = unpredictable positive integer. And I haven't found in ?seq() the particular behavior of this function when length.out = 1. Thanks for your help ! Best, Gael.

I have a problem with the default behavior of seq(), which gives the argument "from" when the argument length.out = 1. This behavior is annoying when the number of value determine in length.out is not predictable. Would it be possible to add an argument that propose the median/mean, i.e. (from + to) / 2 when length.out = 1 ? Examples: > seq(from = 1, to = 11, length.out=1) # current method gives "from" 1 > seq(from = 1, to = 11, length.out=1) # alternative method gives the > intermediate value of "from" and "to" 6 Many thanks for your help.
